For representing color images in RGB, the red, green and blue components are stored as what organization of grayscale images that are recombined later?

• A. Color Maps
• B. Color Planes or Channels
• C. Gray Scale
• D. Planes of Color

Answer: (B)

RGB color data is kept as separate grayscale images for each color channel—one plane for red, one for green, and one for blue. Each plane stores the intensity of that color at every pixel, so you effectively have three grayscale images that line up pixel-for-pixel. When displaying, these three planes are combined per pixel to form the final color by using the red, green, and blue intensities together. This organization also makes it easy to process or adjust a single channel without affecting the others. Palette-based color maps aren’t used for this RGB arrangement, and a single grayscale image wouldn’t capture the separate color components needed to recreate full color.
